Configuration File

; example configuration file for avrreref/cntreref

; rule for virtual reference calculation
[reference calculation]
CZ             ; the CZ channel is the new reference

;CZ, FZ, PZ    ; the mean of the listed channels is the new reference (CZ+FZ+PZ)/3

;CZ * 0.5      ; CZ * 0.5 is the new reference

;all, -CZ      ; the mean of all channels, except of CZ, is the new reference


; list of channels for rereferencing
[reference subtraction]
all, -eogv, -eogh   ; the virtual reference is subtracted from all channels,
                    ; except of EOGV, EOGH

;F1, F2, F3         ; the virtual reference is subtracted from the listed
                    ; channels only

; create a new channel in the output file which stores the virtual reference
;[reference insertion]
;REF                 ; label of the new channel
